Release History

Unreleased (see master)

0.5.2 (2019-05-16)

  • Fixed a subtle bug when signing a multisig transaction over multiple inputs

0.5.1 (2019-04-19)

  • New: Add get_transaction_by_id() calls

  • Update default fees

  • Multisig improvements

0.5.0 (2019-03-10)

  • New MultiSig adds support for P2SH nested m-of-n multisignature contracts

  • Support for sending to P2SH and Bech32 output addresses

  • P2SH nested segwit addresses for PrivateKey and MultiSig

  • Support for batching transaction inputs from different keys

  • Update transaction message length limit to 80

0.4.3 (2018-03-11)

  • Fixed fee calculation when ``combine=False`

  • Breaking: Exceptions will now be raised when using pay2sh addresses (until implemented)

0.4.2 (2017-12-09)

  • Optimized network API priorities

  • Fixed Smartbit pushtx usage

  • Updated 21.co to earn.com

0.4.1 (2017-11-01)

  • Removed blockr.io network backend as Coinbase has shut it down.

0.4.0 (2017-04-19)

  • Changed elliptic curve backend from OpenSSL to libsecp256k1. This results in an order of magnitude faster key creation and signing/verifying.

  • Improved performance of base58 encoding/decoding.

  • Breaking: Dropped support for Python 3.3 & 3.4.

  • Breaking: verify_sig() now returns False for invalid signatures instead of raising an exception. Also, strict is no longer a parameter as BIP-62 compliance is now required.

0.3.1 (2017-03-21)

  • Fixed cold storage workflow.

  • Improved performance of private key instantiation.

0.3.0 (2017-03-20)

  • Implemented a way to use private keys in cold storage.

  • Changed the default timeout of services from 5 to 10 seconds.

  • Fixed network service redundancy by failing if response code is not 200.

0.2.0 (2017-03-17)

  • Improved stability of network tests.

  • Added verify_sig().

  • Refactored crypto to yield over an order of magnitude faster hashing.

0.1.0 (2017-03-15)

  • Initial release.
